The demo so far is looking pretty good, but it lacks a few features that I think are essential to this kind of game, such as a touhou-like "focus" button, that shows the hitbox of the character and slows movement for more precise shots. Also, in trying to stay bullet-hell like but also faster paced it becomes very quickly totally chaotic even on the normal difficulty - I couldn't tell what was even shooting me half the time.
Overall though, this is a good start, but it needs a LOT of work.
There is a Focus button. It's "Z". It was covered in the Tutorial. Perhaps I'll make Shift do a quick focus as it's something more familar.
I'll reconsider the pacing of the game. too
Thanks for your comment.
